SAS Australia 1-7

Survival. A night beasting claims another withdrawal. The recruits come under attack and capture before being facing each other in hand-to-hand combat.

Adaptability. Entering a dark tunnel filled with obstacles and water, recruits must remain adaptable and battle claustrophobia. Tensions boil over as the recruits attempt to work together.

Pressure. A rare morning of good morale is destroyed by a worrying accident before a high-pressure tactical driving task. The recruits reveal their most shameful moments and emotional confessions.
